PATENT EMANUEL ll. OASE, OF MOUNT VERNON, HISSOURI.

FEED-SHOPPING APPARATUS.

SPECIFIQATION forming part of Letters Patent No. 552,820, dated January "1', 1896.

.To aZZ'wi-om it may concern:

Be it known that I, EMANUEL ll. CASE, a citizen of the United States, and a resident of Mount Vernon, in the county of Lawrence and State of Missouri, have invented certain new and useful Improvements in Feed-@hopping Apparatus; and l do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to ina-ke and use the saine, reference being had to the accompanying drawings, which form a part of this specication.

My invention relates to apparatus for grinding or chopping wheat, corn, and other like substances for feeding to stock, and its object is to provide an improved construction of saine which will possess superior advantages with respect to oiiiciency in use.

The invention consists in the novel construction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings, Figure l is a longitudinal sectional view of a feed grinding or chopping apparatus constructed in accordance with iny invention. Fig. 2 is a plan view of the saine.

In the said drawings, the reference-numeral l designates four uprights connected together by end bars 2 and side bars 3, forming a rectangular frame.

The numeral 5 designates a series of intermediate bars parallel with the bars 3.

Journaled in bearings on one of the side bars 3 and one of the bars 5 is a shaft G, provided with a bur 7, having a series of peripheral corrugations or beveled ribs S at equal distances apart and extending from end to end of the bur. The buris also provided with heads 9. The shaft at one end is provided with a cog-wheel l0, with which meshes a larger cog-wheel l2 on a shaft 13, provided with a crank li. llleshing with the cog-wheel l2 is a siniilar wheel l5 on a shaft- 16, provided with a crank 17. This latter wheel and shaft are for furnishing additional power t-o turn the bur and may be dispensed with, if desired. At the opposite end shaft G is provided with a ily-wheel i8 and also with a pulley lil, which may be connected with any Application filed September l1, 1895. Serial No` 562,196. (No model.)

suitable motor for driving' the apparatus by power.

Secured to the bars 3 at one side of the apparatus and to the top and bottoni bars 5 are two horizontal aligned boards 20, each provided with a rectangular aperture 2l. These boards are secured in place by means of bolts 23, which pass through slots in the ends of the boards. These boards are held in place by means of nuts 2l, provided with fingen holds 25.

The numeral 2G designates a vertical stationary bur concaved on its inner side and formed with a number of eorrugations or ribs, the distance between which gradually decreases froni top to bottom. The said corrugations or ribs are inclined on their lower sides and straight on their uppersides, forining cutting-edges. This bur has its upper and lower ends eut away, forming lugs a, which fit in the rectangular apertures in the boards 20, and interposed between the said bur and the outer end of the apertures are rubber or other elastic cushions or springs 20h, which allow the bur to yield slightly, so as to avoid injury to the apparatus should it become clogged.

Secured to the bars i? at one end of the apparatus are cani-levers 27, which are adapted to engage with the boards 20, so as t-o adjust the latter and regulate the distance between the burs.

A drawer 2S is located at the lower part of the apparatus to receive the ground or chopped grain as it coines from the burs, and at the upper end the stationarybur is formed with side walls 29 and a front wall 30, forniing a hopper to direct the grain to the burs.

The operation will be readily understood. The set-nuts are loosened and the cani-levers operated so as to adjust the stationary bur, when the nuts are tightened to hold the bur and its boards in place. The rotating bur is now operated either by hand or power and the grain to be chopped or ground introduced into the hopper, from whence it will fall on the rotating bur and be carried between it and the stationary bur and ground or chopped by the beveled ribs or corrugations.

An apparatus constructed as above will be ICO very efficient in use and will occupy but little space, and being of but little Weight can be readily transported from place to.place.

Having thus fully described my invention, what I claim is- 1. In a feed grinding or chopping apparatus,

-the combination with the frame, and the ro a head at each end and means for rotating said bur, of the horizontally adjustable boards formed with slots near each end and with rectangular apertures, the screw bolts passing through said slots, and the finger nuts, the vertical bur having lugs at the ends engaging with apertures in said boards, having its inner side concaved and formed with corrugations or ribs at varying distances apart, the springs interposed between said bur and the walls of the rectangular apertures therein, and the hopper, substantially as described.

In testimony that I claim the foregoing as my Own I have hereunto affixed my signature in presence of two witnesses.
